So if a polypeptide chain of 214 amino acid residues has 21 basic and 15 acidic residues, the protein :

a) is amphipathicb) will be positively charged at neutral pHc) unlikely to be found inside cells because it is too highly chargedd) will have no net charge at pH 7e) would be expected to form 15 ion fairs

I think its between b and c but I'm not sure which one. And does amphipathic only apply to polar/non polar, and not acidic/basic, right?
